I'm looking for IR commands from an LG TV Remote, Apple TV Remote, and Direct TV DRE remote.

I'm looking for some further assistance as the formatting of codes I received in this reply ([Link: remotecentral.com]) looks different than what we need, maybe someone could help me get this right?

This is an example of the code formatting we need for the above remotes-

Button Code Customer Code Format
POWER 12 0x88FD NEC(uPD6121G)
MUTE 0F 0x88FD NEC(uPD6121G)
UP 20 0x88FD NEC(uPD6121G)
DOWN 21 0x88FD NEC(uPD6121G)
LEFT 22 0x88FD NEC(uPD6121G)
RIGHT 23 0x88FD NEC(uPD6121G)
VOL+ 47 0x88FD NEC(uPD6121G)
VOL- 1A 0x88FD NEC(uPD6121G)
CH+ 13 0x88FD NEC(uPD6121G)
CH- 19 0x88FD NEC(uPD6121G)
PLAY 43 0x88FD NEC(uPD6121G)
PAUSE 46 0x88FD NEC(uPD6121G)
STOP 1B 0x88FD NEC(uPD6121G)
REW 4E 0x88FD NEC(uPD6121G)
F.F 24 0x88FD NEC(uPD6121G)


We have 15 keys to obtain IR codes for-

1) Switch to HDMI 2 / LG TV Code
2) Up button on the directional pad = Up directional
3) Left Button = Left directional
4) Down Button = Down directional
5) Right Button = Right directional
6) Ok button = Enter / select
7) Switch HDMI 1 / LG TV Code
8, 9) Volume = Volume Up, Volume Down
10, 11) Page = Channel / Page up and down on
12) Open guide - Direct TV
13) Mute
14) Arrow Back
15) Power on / Power Off

Is anyone that could provide some assistance with this?

Looking forward to getting this worked out, thanks for reading!

I'm afraid it is impossible to represent all of those in the posted format (only works for NEC, i.e., LG TV). Will pronto hex work for you?

What software are you using that requires the posted format?

For other interested readers, the "NEC(uPD6121G)" bit is a remote control transmitter chip part number. The other numbers are the OBC, device and subdevice for an NEC1 (presumably) signal. There is simply not enough data in this structure to represent Apple TV or DirecTV signals in sufficient detail to be usable by any device or software. "DRE" remote uses the same codes as all other DirecTV remotes.

I can't quite work out what device the posted example is for. There are virtually no devices that use such a device number (136.253). Where did those come from?

OP replied by PM that only the posted format is acceptable. In that case, nothing more can be done.

What I'm being told is their preferential protocol for IR remote controls is NEC, RC5 and RC6, is there any way to translate the 3 remotes we need to those requirements?

Pronto Hex could be an option, could that translate to the IR functions we need with each remote?

Here's what I found here on Remote Central for LG TV Codes.

If I could get a format like this for Direct TV and Apple TVs, does anyone think this would translate to our requirements?

Your LG codes can easily be translated.

POWER 12 0x88FD NEC(uPD6121G) in your example would become

POWER 08 0x04FB NEC(uPD6121G) from your table, or possibly

POWER 08 0xFB04 NEC(uPD6121G) depending on what they expect for low byte and high byte

ATV and DTV are none of the above protocols. Apple has its own protocol, and DirecTV is Russound protocol. There is no need to translate pronto hex for those. We already know function, low custom and high custom for every ATV and DTV command. Problem is they have no way to use the correct protocol. If you join the JP1 forum and download Remote Master and open these 2 files, then Function = OBC, Low Custom = Subdevice, High Custom = Device (low and high might be reversed).

As I said via PM, the company building your remote is incompetent. You picked the wrong manufacturer if their remote can only do 2 protocols essentially (NEC and RC5/6). Other universal remote makers can do hundreds.

If you only need a few hundred of these, just get some cheap JP1 remotes ($3-$4 ea.) plus a JP1 cable ($8), and you can load all your commands into each in about 3 seconds. Even if you had a few thousand remotes, one of your employees could load all of them in a few hours.

Thanks for the information Dave, much appreciated. I'm going to see what I can do with Remote Master and what you linked me to, see where this journey goes.

I'm fairly sure the manufacturer can work with more than RC 5/6, so will see what they come back with. This wouldn't be an issue if my shipment of sample remotes to them was held up in transit by USPS.

Seems strange that a remote company would need any samples considering there are tens of millions of the models you have and that all the codes are well documented and have been for many years. It's as if they have no fundamental understanding of how remotes work. Will be interesting to see how this turns out.
